Google has released to the public a new app called Hands Free, which lets people pay for items in stores by simply telling the cashier, "I'll pay with Google." The app, available for Android and iOS, is only being piloted in a few locations in the San Francisco area, including some McDonald's and Papa John's restaurants. Hands Free works by tracking your location using Wi-Fi and other sensors in your smartphone to detect whether you're near a participating store. After you say "I'll pay with Google," the cashier confirms your identity by using your initials and the photo you've loaded onto the Hands Free app.
